Hi I've got a problem, Im using a Mega2560 and it s not working. Does anyone knows how to solve this problem. I'm testing the code below , but the problem is the pin, cause I've read somewhere that i can not use the pin D0 to d9 as serial. And I don t know how to solve it./*SparkFun Cellular Shield - Pass-Through Sample SketchSparkFun ElectronicsWritten by Ryan Owens3/8/10

void loop() { //If a character comes in from the cellular module... if(cell.available() >0) { incoming_char=cell.read(); //Get the character from the cellular serial port. Serial.print(incoming_char); //Print the incoming character to the terminal. } //If a character is coming from the terminal to the Arduino... if(Serial.available() >0) { incoming_char=Serial.read(); //Get the character coming from the terminal cell.print(incoming_char); //Send the character to the cellular module. }}

Mine simply repeats SIND 1 and SIND 10 about every 10 seconds with about 5 characters of jibberish in between. Does anyone know what could cause this? If I'm lucky I may get a SIND 3 after 10 minutes and once got a SIND 4 and SIND 7. I'm using the development board connected directly to a computer and have change BR to 9600 and band to 7.
